Root Cause

Client streaming code calls stream.Send after stream.CloseSend() or after the server already sent a terminal status, violating the client-stream state machine.

generic

中文

客户端流式代码在 stream.CloseSend() 之后或服务端已发送终止状态后调用 stream.Send，违反了客户端流状态机。

Workarounds

  1. 92% success 
    for _, item := range items {
  if err := stream.Send(item); err != nil {
    return fmt.Errorf("send: %w", err)
  }
}
if err := stream.CloseSend(); err != nil { return err }
resp, err := stream.CloseAndRecv()
  2. 85% success 
    if err := stream.Context().Err(); err != nil {
  return err
}
stream.Send(item)

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Stream is already closed; subsequent sends keep returning Aborted.

  2. 85% fail

    Streams are single-use; a new client.Upload(ctx) call is required.
